Mario, I think you made a mistake a 3:50. Temperature difference is 11°C, desired indoor temp. is still 21, so maximum outdoor temperature for modulation should be 10°C (21-11=10)... Am I correct? Pozdrav i hvala!
Zdravo Mario, imam tcap 9kw i radi samo podno i sanitarni boljer bez pufer. Reci mi koji radni tlak treba da pokazue onaj manometar koji e na unitrasna edinica. Kod.mene e 1-1.5 bari.
Hello. Very interesting calculation. I have a Vaillant arotherm plus Hp, and I simulated these calculation on Vaillant figures. Flow rate is fixed (860l/h), DT in 5 most of the time, and is 2 or 3 only when warmer outside. I have some 135l system, no buffer, and I do not see cycling upto ~ 10C outside. Are these calculation maybe only for Panasonic HP?
Hi, the calculation is general, but more variables need to be considered such as type of the house, temperature range, etc. But that 10 C makes sense for such a model. I assume 5 kW unit?
Greetings from Uruguay. Your videos are very informative and with good technical background!
Thank you very much!

Hi, yes, you are right. I made a calculation if the number will be 6.8-3.14 =3.66 kW.
Thank you for feedback!
So how do you calculate system volume?
Sum up all the pipes/buffers (heating system volume).

dali je to dobro ili ne. Cuo sam da treba biti 2 bar

Yes, exactly the 5kW unit
So approx. 30 L/kW. Sounds good
If you ad more radiators instead of aditional buffer wont be better ? You can even run on lower flow temp after
Yes, sure, but sometimes it is not possible to change radiators or put bigger
Ako zelimo da dodamo vise vode sistemu u vidu volumizera da li ga dodajemo na hladni ili topli vod?
Neko pravilo je na povratu, ali može i na polazu. Bitno je povećati volumen sustava.
@@HVACEducationHub Hvala na odgovoru. na 4:39 kazete da jedinica od 7kW ima 9l u minuti, zar nije 19l po formuli iz prethodnog videa?
To je minimalni protok kad radi s 3 kW
@@HVACEducationHub e sad je jasno. Hvala puno
